Sasaki structures on general contact manifolds

Katarzyna Grabowska, Janusz Grabowski, Rouzbeh Mohseni

We extend the notion of a Sasakian structure from the classical setting of a cooriented contact manifold, where it is given by a compatibility between a contact form and a Rie…

Equivalence functors in graded supergeometry

Katarzyna Grabowska, Janusz Grabowski, Mikołaj Rotkiewicz

It has recently been proved that the category of N-manifolds of degree , that is, -graded supermanifolds of degree for which the parity agrees with the gradation,…

Graded supermanifolds and homogeneity

Katarzyna Grabowska, Janusz Grabowski

We introduce the concept of a homogeneity supermanifold, which is, roughly speaking, a supermanifold equipped with a privileged atlas whose coordinates carry prescribed (real) homo…

Nijenhuis operators on Banach fibration

Katarzyna Grabowska, Janusz Grabowski

In the infinite-dimensional Banach setting, we consider general smooth Banach fibrations and `-tensors' that are projectable (in the obvious sense…

The regularity and products in contact geometry

Katarzyna Grabowska, Janusz Grabowski

We study regular contact manifolds whose Reeb vector field is complete and prove that they are canonically principal bundles with the structure group or

Principal bundles in the category of -manifolds

Andrew James Bruce, Janusz Grabowski

We introduce and examine the notion of principal -bundles, i.e., principal bundles in the category of -manifolds. The latter are higher graded exten…
